In aqueous alumina minerals (monohydrate diaspore, sanshui diaspore, etc.) as the main composition of high bauxite;
The family of sillimanite minerals (including kyanite, andalusite, sillimanite, etc.);Synthetic raw materials, such as industrial alumina, synthetic mullite, fused corundum and so on.China high alumina bauxite resources, quality is good, producing area are mainly distributed in shanxi, henan, hebei, guizhou,
shandong and other places.Produced by high aluminium vanadium and soil, mainly diaspore monohydrate (alpha Al2O3 · H2O) and kaolinite and the mixture of two kinds of minerals.\ n high bauxite with rotary kiln and vertical kiln calcination, sintering temperature of 1500 ~ 1700 ℃.
Sintered bauxite, bibulous rate is in commonly 4 to 7%。
3 oxidation 2 aluminium (Al2O3) content higher than 48% of the silicate aluminum refractory products.Such as Al2O3 content higher than 90%,
called corundum brick.Due to different resources, the national standard is not entirely consistent.Such as European countries for high aluminum
refractory Al2O3 content lower limit is 42%.In China, according to the high alumina bricks are usually divided into three classes: Al2O3 content in Ⅰ etc. ─ ─ the Al2O3 content > 75%.Such as Ⅱ ─ ─ Al2O3 content is 60 ~ 75%;Such as Ⅲ ─ ─ for 48 ~ 60% Al2O3 content.
The raw material According to the resource conditions and different requirements for products, can use the following categories of the material: with water alumina minerals (monohydrate diaspore, sanshui diaspore, etc.) as the main composition of high bauxite;The family of sillimanite minerals (including kyanite, andalusite, sillimanite, etc.);Synthetic raw materials, such as industrial alumina, synthetic mullite, fused corundum and so on.China high alumina bauxite resources, quality is good, producing area are mainly distributed in shanxi, henan, hebei, guizhou, shandong and other places.Produced by high aluminium vanadium and soil, mainly diaspore monohydrate (alpha Al2O3 · H2O) and kaolinite and the mixture of two kinds of minerals.

- Q: Is there a big difference between two high alumina brick and one high alumina brick?
- The difference between the two kinds of high alumina bricks is great. I perennial in Zhengzhou was responsible for the production and sale of colt refractories
- Q: Introduction of high alumina brick
- Three alumina silicate refractory product with a content of two Al2O3 (48%).
- Q: What is the standard classification of high alumina bricks and high alumina bricks?
- High alumina brick is a kind of refractory material in refractory brick products. It is made of refractory clay or other refractory material. It belongs to the product of Si Al System
- Q: What are the reasons for the decline in the performance of high alumina bricks when we use high alumina refractory bricks?
- Quality requirements for aluminium bricks of different grade. 2, high aluminum powder and high alumina aggregate and other materials of reasonable proportion, to reach the production requirements.
- Q: What is the density of a super high alumina brick and what is the price?
- Super high alumina brick, alumina content of 80% bricks, bulk density of 2.7g/cm3 or more, the factory price of about 1900 yuan
- Q: How to make refractory bricks and boiler wall adhesion more firm?
- Suggest that you use fire brick to increase the length of brick or pull the amount of turn, and use high temperature mortar masonry
- Q: Which is faster for heat transfer between corundum bricks and high alumina bricks?
- 75 high aluminum and 43 clay bricks, 75 single weight 4.5kg or more. 43 3.65kg or so, the use of temperature 75, high aluminum in about 1520, 43 of brick 1430 or so, the color of 75 pan white, 43 of the Loess color. In short, the difference is great.
- Q: Corundum, high alumina and fireclay refractory difference is what
- Corundum is unknown. The high alumina brick has higher aluminum content than the clay brick, and the temperature resistance is higher than 300 degrees. It is more durable and durable than the clay brick. The production process of high alumina brick is better than that of clay brick. For example, the weight of good clay brick is 3.7kg, and that of high alumina is 4.2kg. Good density. But the price of high aluminum is too high: ordinary clay brick (standard brick example) in 1.1--2.5 yuan / block, high aluminum to 4.5 yuan / block, or even more expensive. The extra high aluminum has reached 5000 tons. Say straight white point is: under the same conditions, clay brick for a period of one year, then the high aluminum for more than three years.
- Q: The difference between light high alumina brick and heavy aluminum brick
- Lightweight high alumina bricks, commonly called insulating refractory bricks, also known as insulating refractory bricks. First of all, literally, lightweight aluminum bricks and heavy aluminum bricks are very different in weight. Lightweight high alumina bricks, also called insulated high alumina bricks, are designed for insulation and heat preservation. In normal use, the utility model is not directly contacted with the furnace temperature, and is a refractory brick product which is close to the furnace wall and has the function of heat insulation and heat preservation.
- Q: High alumina brick 80 with which high aluminum cement?
- In order to maintain a reasonable comprehensive lining, should adopt high quality aluminum refractory mud, such as Sichuan resistance card phosphate refractory mud, refractory clay, high alumina refractory mud PA-80 LN-75, if you use the card volume of Sichuan resistant refractory clay masonry, the effect is better.
